Common Symptoms
- Power window won't go up or down — stuck in current position
- Power windows not working — no response when activated
- Window moves slowly or only works from one switch
- Infinite resistance in the power window circuit — broken wire or disconnected connector
Possible Causes
- Broken wire or connector pin in the power window system harness — common at flex points like door jambs or where wiring moves
- Disconnected or loose electrical connector — may have been bumped during other repairs
- Failed window motor/regulator — internal open circuit from age, heat cycling, or vibration
- Corrosion completely severing a wire or connector terminal — green crust on copper wiring
- Wiring harness damage from rodent chewing — look for nesting material near the engine or under dash
- Window regulator mechanical failure — cable snapped or pulley broken, motor runs but glass doesn't move
Common Fixes
- Scan vehicle with a professional-grade OBD2 scanner to read all stored codes and freeze frame data — note the conditions when the code set ($49-88 at shop, free at auto parts store for basic scan)
- Visually inspect the power window system wiring harness and connectors — look for chafed wires, melted insulation, green corrosion, loose pins, or rodent damage (often free to check yourself, $114 diagnostic fee at shop)
- Trace the power window system wiring from connector to connector with a multimeter set to continuity/resistance mode — find and repair the break in the circuit ($83-483 labor for diagnosis and repair)
- Check and reseat all connectors in the power window system circuit — disconnect, inspect pins, clean with electrical contact cleaner, apply dielectric grease, and reconnect firmly ($11 DIY or $93 shop minimum)
- If window motor/regulator has failed internally (open circuit inside), replace it — don't try to repair sealed components ($100-500)
